The document provides updates from the Texas Water Development Board Groundwater Division. It introduces two new program managers, Kristie Laughlin as the BRACS Manager and Robert Bradley as the Groundwater Technical Assistance Manager. It also provides information on upcoming groundwater models and research projects to support model development. These include models for the Gulf Coast Aquifer, Edwards Plateau Regional Aquifers, Northern Edwards (BFZ) Aquifer, and others. The document requests water quality data from stakeholders and discusses databases and a national groundwater monitoring network that TWDB is involved with. It provides contact information for Natalie Ballew for any questions.
